Documentation

Class that encapsulates a "real time" HV channel. Its purpose is to allow access to a PHENIX HV channels in real time, i.e. the individual HV channels that are controlled by EPICS.
The EPICS extension ezca (easy channel access) is used to access the EPICS database in the IOC.
Note: Currently we only support 1461Nmod104 modules and will have to add the others later.
MODIFICATIONS:

support for the 1469 modules:
The LeCroy 1469 modules consist of two types of channels: 3 bulk supplies with 8 physical channels each. The bulk supplies look like real HV channels, whereas the indiviual channels have fewer properties (i.e. No DV, RUP, RDW, MVDZ). We make the corresponding member functions virtual and add a class for handling the bulk supplies and the individual 1469 channel.
